US12624933 - High kinetic energy hollow bullet

The present invention relates to an innovative hollow bullet design, which fundamentally diverges from conventional solid bullet configurations. This design encompasses a brass casing, gun powder, a plastic wad, and a distinctively structured nozzled projectile. The nozzled projectile features a hollow portion that starts wider at the proximal end and narrows towards the distal end, ingeniously manipulating airflow to enhance kinetic energy during flight. This unique aerodynamic efficiency potentially increases impact force and stability over extended distances. The bullet maintains standard size and weight, ensuring compatibility with existing firearms, and offers significant improvements in performance for both civilian and military applications.

This design allows for compatibility with existing firearms while improving performance for both civilian and military use.

Claim 1

1 . A bullet comprising: a casing; a wad disposed within the casing; a nozzled projectile operatively coupled to the wad; wherein the nozzled projectile is hollow and includes an internal tapered structure extending longitudinally from a proximal end which is a tip to a distal end, and further wherein the internal tapered structure is configured to facilitate airflow during flight of the bullet, thereby enhancing the kinetic energy of the bullet, and wherein the nozzled projectile has a point located adjacent to the proximal end which is wider in diameter than the proximal end, and wherein the nozzled projectile widens in diameter and is conically shaped from the point adjacent the proximal end to the distal end. a casing; a wad disposed within the casing; a nozzled projectile operatively coupled to the wad; wherein the nozzled projectile is hollow and includes an internal tapered structure extending longitudinally from a proximal end which is a tip to a distal end, and further wherein the internal tapered structure is configured to facilitate airflow during flight of the bullet, thereby enhancing the kinetic energy of the bullet, and wherein the nozzled projectile has a point located adjacent to the proximal end which is wider in diameter than the proximal end, and wherein the nozzled projectile widens in diameter and is conically shaped from the point adjacent the proximal end to the distal end.
